New - and worrisome - contaminants emerge from oil and gas wells - Researchers find alarming levels of ammonium and iodide in #fracking wastewater released into #Pennsylvania and #WestVirginia streams. The toxic substances, which can have a devastating impact on fish, ecosystems, and potentially, human health, are extracted from geological formations along with natural gas and oil during both hydraulic fracturing and conventional drilling operations, said Duke University scientists in a study published today in the journal Environmental Science & Technology. The chemicals then are making their way into streams and rivers, both accidentally and through deliberate release from treatment plants that were never designed to handle these contaminants, the researchers said.
